Natural habitat and enclosure design- 

Bengalese Finches are not found the wild and are instead a species developed solely through domestication! As a result, they have no natural habitat from which to base their care requirements. They are thought to have descended from the White Rumped Munia following generations of captive breeding in Asia. They first appeared in captivity in Europe in the late 1800s and have become a common pet species globally since. 

When it comes to housing birds in the home, there are several main options. These include indoor cages/aviaries, outdoor aviaries, or bird rooms. Below is an overview of the advantages and disadvantages of each housing method. 

• Cages: keeping birds in a conventional cage is without doubt the most common method used by owners. They’re effective, practical options, and generally much cheaper than alternatives, but are not without their drawbacks. Even the largest of commercially available bird cages provide very limited space for natural behaviours, especially for more active and intelligent species such as parakeets and parrots. It can also be incredibly difficult to provide an enriching or naturalistic environment in a cage environment. In addition, whilst cages offer an ideal space for sleeping and eating, most species should have plenty of time outside of their cages each day, in a bird-safe room. When I have housed birds in cages before, I have ensured the cage itself is larger than the minimum requirements for the species and left the cage doors open for much of the day to provide choice and control for my birds. 

• Indoor aviaries: indoor aviaries can be purchased commercially (often at a high cost) or built yourself with relative ease. They offer more space and enrichment value than a typical bird cage and eliminate the risk of predation/pests which may come from an outdoor setup. An indoor aviary could allow a much more natural environment to be created, utilising natural perching and plants. One consideration with commercially made indoor aviaries is their bar spacing. Most are constructed with larger species in mind, and these can have a larger bar spacing, therefore reducing the security of the enclosure for a small species, and posing a greater risk of injury (e.g. trapping a body part). 

• Outdoor aviaries: an outdoor space is always my preferred option for my own birds. This may not always be a suitable housing option and will often depend upon your specific circumstances, such as the species, location, weather, and more. They are by far the costliest option but can offer a much larger and naturally designed space than others when well-planned and constructed. This also allows more birds to be housed, which can be beneficial for species which would naturally occur in social groups. For finches, they are the perfect option, with large floor areas for foraging, open space for flight, and the ability to provide natural planting. My own aviary even has an artificial termite mound alongside a range of natural features! 

• Bird rooms: perhaps the least common method, reserved only for the craziest of bird keepers, is the bird room. For those lucky enough to have a spare room in their houses, they can be converted simply into a perfect enclosure for birds. They can offer much more space than standard cages and have many of the advantages of an outdoor aviary in a more controlled environment. This could be a good option for a keeper looking to provide the space of an outdoor aviary but concerned about predators, vermin, and poor weather. 

For the sake of the remainder of this section, we will look at the requirements of caged Bengalese Finches, as this is the most common method of housing. If you can provide larger environments- indoors or out- I would encourage you to do so. Otherwise, let’s continue... 

Bengalese Finches are small yet active birds. As a result, a cage of at least 80x45x45cm should be offered for a pair. Again, bigger is always better, and I would suggest keepers find the largest cage they can fit into their available space. These birds are a social species, so larger groups can be housed, with the enclosure size increasing to reflect this. Whilst height is beneficial- and many birds will feel most secure at greater heights- the width of an enclosure is more important. Birds fly side to side, not up and down, so a tall thin cage is not at all suitable. All cages should have a bar spacing of between ¼ and ½ an inch, as this will ensure the bird cannot injure itself. When purchasing a cage, ensure you pay close attention to these dimensions, and avoid models which have other larger gaps which could cause injury. 

Perching is one of the most important furnishings for a bird enclosure. In most cases, cages will come with perching. I would recommend setting this to one side and instead collecting or purchasing your own perch materials. Birds will spend the majority of their time on their feet, and inappropriate perching (such as the smooth dowels or plastic tubes included with most bird cages) can be detrimental to their foot health, causing sores and infections. I combine a variety of perch materials and diameters in my bird enclosures, many of which are bird-safe branches collected from outside and disinfected for biosecurity. The natural variety of textures and diameters is great for foot and claw health. Other perch options include rope (care should be taken to ensure there is no risk of entanglement) and flat platform perches, usually constructed from wood. If you are offering plenty of time outside of the cage, the cage itself can be designed more as a ‘playroom’, densely packed with perching and toys. 

Finches are unlikely to utilise traditional bird ‘toys’, which are generally best suited to parrots and parakeets. Instead creating an environment with a variety of perching options and space to exercise is most important. If you do wish to offer toys, opt for small, lightweight options, and ensure that there are no small parts which could cause injury to smaller finch species. 

Environmental conditions- 

In an indoor environment, there is no need for supplementary heating or lighting, provided the cage can be situated in a draught-free, well-lit area, out of direct sunlight. Whilst individual bird’s needs will vary, Bengalese Finches are often considered hardy, social birds. As a result, it is likely they will thrive in a high traffic area of the home, such as a main living space. Just be mindful of the common threats to birds around the home, which can be found here. 

Some keepers will offer birds housed indoors supplementary UV lighting due to its importance in synthesising Vitamin D, just like in humans. This is still a relatively new husbandry development and being heavily researched for various taxonomy. Studies suggest exposure is important, however it should be carefully controlled to prevent health issues, much like in mammals. 

If housing your birds outdoors, a draught-free indoor sheltered area will be required. To maintain an ideal temperature, a heater may be required dependent upon temperatures and weather conditions in your area. 

Diet and feeding- 

A large part of a wild bird’s day will be spent foraging and feeding. Therefore, it is important that their daily allowance of food and water are available throughout the day. 

Contrary to popular belief, the diet of a captive birds should be varied, including a range of fresh and formulated foods. An all-seed diet is not suitable and can be detrimental to an animal’s overall health with its high fat content. The bulk of a Bengalese Finch’s diet should be made up of seeds and fresh foods. Most keepers will recommend a diet of: 

• Seed: to prevent issues such as selective feeding and obesity it is important that seed is not fed exclusively. A high-quality seed mix is important for the health of your bird, and high-fat mixes should be avoided. Commercially available mixes for Australian finch species can be found easily. Overall, a seed mix should make up around 50-60% of the daily intake. 

• Fresh food: a wide range of safe fruits and vegetables can be offered to your birds. Birds may show a preference for fruits due to their high sugar content, but variety is important. To save time and reduce waste, large batches of fresh food can be prepared in advance and frozen for later use. Just thaw all frozen food in the fridge overnight. Fresh foods should make up the remaining 40-50% of the diet. 

• Other feed items: the typical diet for your Bengalese Finches should be made up of seed and fresh feeds, however additional foodstuffs can be fed to vary the diet and provide a more natural range of feeds. Whilst pellets are not as important to finches as many other pet bird species, they can still be offered in small quantities to ensure your birds are getting their full spectrum of nutrition. Protein sources such as egg and insects can also be fed. 

Provided with the diet above, additional supplementation is not necessarily required, however produts such as Nutrabol, Vionate, and Avimix are available and can be included in line with the guidance on the packaging. 

To reduce predictability, you can change how and where you offer food. This may also help to reduce selective feeding, where animals show a strong preference to certain feed types and do not get the full variety of feed the require. You could move food bowls to different areas of the cage or create several feeding stations for you bird to visit throughout the day. You can also increase feeding time by using dietary enrichment methods, which will be covered more in the next section. 

It is suggested that food and water should be offered in stainless steel bowls. These are easiest to clean, do not harbour bacteria, and are hard-wearing. 

Wild behaviour and enrichment- 

The White Rumped Munia- the Bengalese Finch’s wild counterpart- is a social species and will naturally live in flocks. Keepers should consider whether they wish to house their bird alone or with others of their species. I believe wherever possible social species should be housed in pairs or groups to best meet their phycological needs. When housing animals in social groups, make care to avoid accidental breeding and ensure you have a suitable sex ratio, whilst carefully monitoring behaviour. 

Birds are intelligent animals and require plenty of enrichment to keep their minds active and bodies healthy. Whilst we have already made several suggestions to keep your birds busy, there many more simple ways we can offer our birds to opportunity to carry out their natural behaviours. 

Adding things to the bird’s environment is the simplest way of keeping them stimulated. This could include new perching, feeding areas, or anything else. Similarly, regularly swapping the placement of items, or removing certain features for a short period entirely can be a great way of reducing boredom and encouraging natural exploratory behaviours. I have also included natural foliage into my bird enclosures, which provide new sights and smells, as well as opportunities to climb and chew. This is highly effective enrichment for finch species, which I believe benefit more from having natural enclosure features than bird toys. Ensure the browse offered is from a non-toxic plant and free from disease risk. 

Dietary enrichment is also an important part of husbandry and is a great way of increasing the time taken for your bird to eat to more natural durations. Novel or high-reward feeds could be offered on occasion for variety. This could include items such as sprouts, larger seeds, and live invertebrates. It can also be more interesting for your birds if the standard diet is varied, for example using different fresh feed items throughout the week. It can also be presented in different ways, such as chopped, roughly chopped, or left as larger pieces. Smaller fruits and vegetables could even be speared on perching. Forage feeders, which could be as simple as a shallow tub of substrate and seed and be great for prolonging feeding time and encouraging natural foraging behaviours. 

Birds are also built to fly, and flight is vital for staying healthy. A larger cage or aviary will allow for this. Indoor birds will also benefit from regular exercise outside of the cage in a safe, secure room. 

Breeding Bengalese Finches is generally considered to be an easy process, with little intervention required so long as the housing is correct. They are known to be excellent parents and keepers will sometimes use them as surrogate parents for neglected chicks of other species! 

Health and disease prevention- 

As with any pet, these birds can contract to several different illnesses, including mites, worms, bacterial infections and more. Birds require very specialist care, and many standard domestic veterinary practices will not be able to provide for the specific needs of avian patients. As a result, it is important to register your bird with an approved avian vet. Veterinary care can be very expensive, so ensure you have the means to cover any unexpected costs or consider insuring your pet. 

• Mites- there are numerous mites that can affect bird such as Air Sac Mites and Scaly Face/Foot mites. These are often simple to cure using easily obtained treatments, although it is best to consult your avian vet, especially in advanced circumstances. Unfortunately, scaly face mites are something we have had to deal with in our aviary, although happily the issue was quickly spotted and controlled. Quarantining new birds and using preventative mite treatment will ensure safety of any birds already in your home. 

• Plucking and self-mutilation- when birds over groom themselves or each other, it is often a sign that something is wrong. Whilst it can indicate a health problem or skin issue, it is most associated with stress or boredom and considered a stereotypical behaviour. Providing an enriching environment will reduce to likelihood of these issues. 

• Egg binding- this is where females are unable to pass eggs, often due to poor diets and lack of essential vitamins/minerals. If immediate vet treatment is not provided, it's likely your bird will not make it, as they often cannot pass the eggs on their own. A proper diet, including as much variety as possible, will reduce the chances of this occurring. 

• Bacterial infections- there are numerous bacteria that can cause illness, and far too many to list here. Consult your vet immediately if you see any signs of a bacterial infection, which includes nasal discharge and watery eyes, along with other symptoms. Regularly cleaning enclosures and their environment, along with setting up new birds in quarantine, will minimise risk of such infections. 

• Viruses- viruses in pet birds are often highly contagious. For example, Avian Flu is dangerous in wild birds, and if not properly protected during an outbreak, aviary birds can easily pick it up, and your entire flock would have to be culled to prevent further spread. Some viruses are treatable with veterinary care, so contact your vet at the first signs of a virus for diagnosis and treatment.
